METHOD OF PROCESSING RIGID BODY INTERACTION IN PARTICLE-BASED FLUID SIMULATION

摘要

A method of processing a rigid body interaction in a particle-based fluid simulation includes determining a collision direction based on a normal vector of a pair of input particles and confirming whether parent objects of the particles actually collide against each other after the determination, and calculating a perpendicular impulse based on properties of the parent objects when the collision is confirmed. The method further includes calculating a final collision based boundary force by applying a tangential friction force to the calculated perpendicular impulse to apply the final collision based boundary force to the respective particles.
